Easton MAXUM ULTRA -3 BBCOR Baseball Bat: BB21MX

The MAXUM has been rejuvenated for this release and should be cranking dingers to leftfield, centerfield and rightfield!

Bat Benefits

This MAXUM Ultra presents a rare one-piece, all-composite design on a BBCOR bat. With this bat you will get the stiff feel that one-piece bats provide and it will feel like all the energy you put into your swing gets transferred into the baseball. As well, the barrel profile of this bat is going to be huge and therefore the sweetspot will be humongous. Lastly, do not forget about the re-balanced swing feel of this MAXUM Ultra BBCOR bat. Compared to the previous model, Easton added a little more heft to the barrel to allow power hitters to feel like they can really crush. However, contact hitters, don't be worried, you should still be able to whip this bat through the zone!


Easton is a stand-up outfit and because of that, they extend a twelve (12) month warranty on every bat that they sell. If you purchase this bat from JustBats and experience an issue with the bat within 1 year of the purchase, definitely reach out to the Bat Experts from JustBats. They can be reached on PHONE at 1-866-321-2287, EMAIL via, or by CHAT when you click into the chat box in the bottom right corner of this page. The Bat Experts understand the warranty process for Easton and will make sure you are able to do a successful warranty replacement process with Easton!

What is the difference in this bat and last year's Maxum?
We do not have all the specifics to date on the new Easton MAXUM ULTRA -3 BBCOR Baseball Bat: BB21MX so we are not sure what might be different compared to the Easton MAXUM 360 -3 BBCOR Baseball Bat: BB20MX. Will have a better grasp on this question come December.
Whats the durability like on the BBCOR MAXUM? My son had the -5 for 2 months before it went dead. Easton replaced but seems like quite a bit of money for that amount of time.
Unfortunately, there is no way to say how long a bat will last for. We haven't had a large number of complaints on the Easton MAXUM ULTRA -3 BBCOR Baseball Bat: BB21MX that would make it seem like there are more durability issues than with other bats.
